Kent Raible's Chopper-Granulation Shear

A lever-operated shear for chopping wire into the tiny snippets used in granulation work at the bench. Designed by Kent Raible and made in the USA, the Chopper Granulation Shear is a precision tool engineered for rapid, high-volume production of those snippets. While it resembles a simple shear at first glance, the Chopper incorporates sophisticated engineering that sets it apart from conventional cutting tools.

The key innovation is a spring-loaded stop side that moves down and out of the way as the shear is actuated, eliminating the reset delay that slows conventional shears. As a result, you can cut snippets as small as 0.1 mm in length as fast as you can move the lever. Kent himself reports chopping at up to 8 cuts per second. For even faster production, the Chopper accepts a double load of 0.4 mm wire, yielding twice the snippets per stroke. Kent works primarily with 0.4 mm wire, cutting a variety of snippet lengths mostly under 1.0 mm.

A built-in slide catches each snippet and directs it into an included container, keeping your precious metal cuts secure and organized at the bench.

Features

• Spring-loaded stop side enables continuous rapid cutting without manual reset
• Cuts snippets as small as 0.1 mm in length
• Double-load capacity with 0.4 mm wire for doubled output per stroke
• Reported cutting speed of up to 8 strokes per second
• Integrated snippet slide channels cuts directly into the included collection container
• Maximum repeatable cut length of 10 mm using the built-in stop

Notes

What you get:

• Chopper Granulation Shear
• Collection container for wire snippets

Wire diameters up to 1.2 mm can be cut, with 0.4 mm the diameter the designer works with most.
